Bus Administrator
MVB device with Bus Administrator functionality is able to work as MVB bus
Master. This function supposes the device is able to transfer the Process Data
and Message Data as well as transmit and receive the Device Status type
information.
Electric Middle Distance
This is a type of physical interface of MVB line, where a twisted pair of shielded
wires is used for interconnection with implementing of transformer coupling for
galvanic separation. EMD medium is used for up to 32 nodes and for distances
up to 200 m.
End Setting
The node in this state is physically located at the the end of WTB line, or
between two independent segments. One of MAU channels is connected in
direction 1 and second in direction 2. The WTB line segments, connected in
direction 1 and 2 are disconnected. Terminating resistors are connected in both
directions.
Intermediate Setting
The node in this state is physically located in the middle of WTB line. The main
MAU channel is connected in direction 1 or in direction 2, the auxiliary MAU
channel is deactivated. The WTB line segments, connected in direction 1 and 2
are interconnected. The terminating resistors are disconnected in both
directions.
Line gate (Line Unit)
All HW resources providing the electrical connection of MAU to the WTB line.
Medium Attachment Unit
Part of node which is used as a coupler to transmission medium.
Sleep Mode
In this mode the node goes to End Setting state. Only part of MAU is active.
The node detects valid frames on line.
To Be Defined
Information will be completed in document revision.
TCN Gateway
MVB device with TCN Gateway function is able to access to other buses. This
function supposes the device is able to transfer the Process Data and Message
Data as well as transmit and receive the Device Status type information.
